I have installed and trialled several "cripple ware" utilities over the past couple of years and realise I now have several registry entries related to expiry conditions. I haven't been using TU or inctrl enough: stupid me Have been using FDISR and IFW since recently I am not even sure if those apps (TU & Inctrl) will clean those reg entries? I have found this utility; Registry Trash Keys Finder: http://www.databack4u.com/snc/rtkf_eng.html This claims to be able to ferret out obsolete "limiting" keys. I am NOT interested in cracking any utilities. Any one have any experience of this app and the difference between the free version and the unlocked version: safe? effective? Thanks.
